OAuth 2.0 authentication using Client credentials

[Pragati Yadav1]

Hi, 

I'm trying to generate Access token without username and password. Client have shared Audience parameter I'm not sure where this field will be mapped in ServiceNow platform.

As I try to generate OAuth Token I'm getting the below response. 

Can someone help me with the generating Token succesfully?

HI @Pragati Yadav1  - did you get a solution for this issue. From where did you pass the audience parameter other than the content in the HTTP method in the REST Message. 
We also have this requirement and facing access issue. 

Thank you.
